Hey guys. So i just transplanted into my new soil mix and my plants are looking very unhappy. Its been about a week now and they are still very droopy. Whats interesting is they are still very green and producing new growth (slower than before of course). The mix i put together was supposed to be “no cook time” but after seeing the state of the plants i measured root zone temps and they are about 105 degrees! Do you think they can recover? I mean i know its possible because some strains have recovered already but specifically my goji OG looks like its on the brink of death. I wasnt too worried at first but 8-9 days seems like way too long. Please advise?

Burned by soil mix

They are outdoors in 100 gals. Right after transplant we got very heavy rainfall for about 48 hours straight. Total involuntary flush lol. Im just confused because i figured after 9 days if they hadnt bounced back they were for sure goners , but they seem to be slowly growing still and have good color. Are they gonna make a comeback or did i cook em to death?
I’ve been trying to find an answer on how hot is too hot. Easy to find what optimal root zone temp range is but at what point does damage actually occur? I’ve had AC failures indoor that led to extremely high ambient temps and also hot days growing outdoors where the soil must have reached the high 90s or even hundreds. But i’ve never seen damage like this before
They went from indoor, to hoophouse, to full sun/hot soil. Also we had a few cold rainy days going straight into the worst heat wave ive seen in my area. They getting a rough welcome to the outdoors. Really hoping they bounce back soon. The fact that they have some new growth makes me think that they will, despite this super extended stress period
well i stopped transplanting on my second day when i noticed the wilt. half my crop is still in 5 gals and they seem super happy, even in the heat. i guess cause they havent been disturbed at all they can handle alot more
What is in the mix?
peat, pumice/rice hulls, local compost (mostly cow manure and lobster compost up here in maine. seemed very well composted low odor etc)
then added stuff like gypsum, oyster shell flour, basalt, neem cake, kelp meal, worm castings. nothing too hot like chicken shit or blood meal because i knew i was gonna rush them in without letting it cook. thought it would be totally chill but once everything was mixed it really roasted. maybe i shouldnt have wetted the mix down with a tea? accelerated it too much?

That is still quite a few ingredients and seems strong for a no cook mix.. In some ways the concept of a no cook mix seems silly in a way as it is a bit of a gross assumption or major generalisation as no two bases/composts/manures are the same for one thing.
Common sense would kinda say the more amendments you use in soil the more you would want to give it a good amount of time to let it come alive biologically and then settle down with the right long term non pathogenic microbiome and also allowing more buffering reactions take place so the pH of the mix is less volatile.
Bet ya it's the local compost that is too hot in the wrong N.. Nitrates/nitrites/urea/ammonia etc.. and stress/lockouts possibly from pH swings..
Maybe dig one out and repot it in a different and legit safe soil mix and see how she responds, that will tell you what is doing it.

I agree that it is likely the compost you used that could likely not have been finished, however I am not experienced with using neem cake and I don't know if it is 'hot'. I know it is used in some mixes which recommend 'composting' your mix.
I've never had a problem with your other ingredients. I did have a similar problem once by accidentally mixing in a high ratio of rock dust. The plants did recover but were set back.
A simple test for compost is to plant a tomato seed in it. If it sprouts and grows a few days to a week without burning, usually the compost is good (finished).

Comfortably numb!
Luv your litmus test
well they are finally starting to come around. got a break from the heat wave which helped alot. seems like my mix stabilized. checking temps on the pots that dont have plants in em yet and the temps are stable at around 80 degrees. not bad right? gonna transplant a few more tomorrow and see if just a 5-6 days cook time did the trick.
i'm not sure it was the local compost thats at fault here. many growers in the area use it, and the farm boasts of there long term curing process and carefully screened quality ingredients. they say its mostly "oceanic residuals" like lobster, crab, fish. i have also personally used it on a small scale with my indoor and its been awesome. never cooked the mix with the indoor and the plants always took to it easily. guess it gets alot hotter with larger amounts in larger pots huh? i should have known better.
